These cute concrete planters are an adorable addition to any home or garden! The molds are made of recyclable materials and concrete mix is very inexpensive to buy. You can switch up the plants in these planters to give these little guys a fresh new 'do.

Step 1: Gather Your Supplies

To make the mold, you will need:

  • Plastic pop bottle
  • Marker
  • Scissors and utility knife
  • Tape
  • Drinking straw
  • Cooking spray or petroleum jelly (as a mold release)

To mix and cast concrete, you will need:

  • Concrete mix
  • Safety gear: gloves, mask, safety glasses
  • Container for mixing
  • Water
  • Something to mix with (eg. garden trowel)

To add the finishing touches, you will need:

  • Concrete paint
  • Paintbrush
  • Coconut fiber or potting soil
  • Plants

Step 2: Cut Pieces For Your Mold

You will want to use the upper portion of the plastic pop bottle. Mark where you want your cutting lines to be on your bottle. (Tip for drawing perfectly straight lines: Use a metal clip to hold on to your marker and stick the clip to a magnet on your refrigerator. Then place your bottle so that it is touching the fridge and position the marker so that it is in contact with the bottle. Rotate the bottle all the way around so that you have drawn a line all the way around the bottle.)

To cut the bottle, I first used a utility knife to make a puncture and then I continued with scissors. Once the dome part is cut out, you can work on the inner cavity. You will need to cut a strip from the bottle that is about a half an inch shallower than the dome part

Step 3: Assemble Your Mold

Roll up the strip of cut plastic and place it in the opening at the top of the dome. Let the strip unroll so that it forms a cylinder the same size as the opening. Tape it in place.

Use tape to close the inner tube cylinder at the end that is closest to the large end of the dome. Make a hole in the tape and stick a straw through to make a drain hole.

Coat the mold with cooking spray or petroleum jelly to help the concrete release.

Step 4: Mix & Cast Concrete

I used about 4 pounds of mix for 3 planters and used the amount of water suggested by the instructions. I mixed it in a plastic bucket with a garden trowel. I added the mix to the mold, a little bit at a time, while tapping the mold to try to prevent air pockets. Remember to wear your gloves, mask, and safety glasses!

I cured the concrete for the amount of time the instructions suggested for warmer weather. During this time, I tried to keep the concrete moist. After I removed the concrete from the molds, I soaked the planters in water and vinegar overnight to try and neutralize the concrete.

The bottom of my planters were not completely level, so I sanded them down using a bit of sand and a plank of wood.

Step 5: Finish

Paint on a face with paint suitable paint for concrete.

Fill the planter with coconut fiber or potting soil and add a plant hairdo.


<p>omg these little guys are sooooooooo cute</p><p>(ɔ◔‿◔)ɔ &hearts;</p>
<p>Great idea these look adorable!</p>
These made amazing teacher appreciation gifts. Though I was a bit late with them since curing the concrete took awhile. Now I want an army of the for my garden. Thanks so much for the Instructable
They look great, how long do you cure it for?
<p>I let them sit in the forms for 2 days, trying to keep them somewhat moist. Then I took them out and put them in a water bath for another 3 days before sanding, painting and sealing with a clear coat. This might be a bit over the top, but the crumbling and cracks is what happens when something dries too quickly. I used quikrete but I didn't precisely follow the mixing directions as it was too dry to fill the forms properly. Next time, I think I'll wait one day before I remove the forms (spraying them with water that day) and then 3 in the water bath.</p>
Hi, I tried making planters and a week or 2 later they all developed slight cracks in them, do you think maybe because I sealed the pot 3 days after and should I wait 2 weeks?
Great instructions! Mine came out great. Everyone at work love them and so do I.
<p>They look amazing!</p>
<p>mine looks a bit different.. i am in the process of making a custom smart plant pot. your instructions were very helpful. making a mold is fun and very challenging :)<br></p>
<p>Great Instructable! I'm really glad I found it. I made two this past summer, one for each of my sisters. They both love it! It was tough to find a suitable plant, but I went with a small ornamental one from Lowes. I actually forgot to grease the mold when I poured the concrete, but it still removed really easily.</p>
<p>Awesome! </p>
<p>The things someone can do with concrete are amazing. I recently tried something like this and uloaded an instructable. I went for a bigger planter though.</p>
<p>Very Good!</p>
<p>cute :)</p>
:D sooooo cute!!
<p>Congratulations on being a finalist in the Concrete and <br>casting contest! Best of luck to you!</p>
<p>love these happy face cement planters </p>
<p>Thanks! :)</p>
<p>What happy faces, and your choice of 'do' is very cute.</p>
<p>Thank you!</p>
<p>ha ha ~good!</p>
<p>Awesome Cute .. </p>
<p>Really nice. </p>
<p>Thank you!</p>
<p>These are gorgeous! Kids of all ages will love these and I'm definitely going to make some as presents for a couple of little kids (and a few big kids) in the family. I know they'll be chuffed! Thanks for this instructable!</p>
<p>Thank you for your comment! I'd love to see how they turn out.</p>
<p>So sweet, thaks for sharing :)</p>
<p>Thank you :)</p>
<p>One suggestion, try making them out of <a href="http://en.wikipedia.org/wiki/Hypertufa" rel="nofollow">hypertufa</a> so they will be lighter, and drain better. My wife makes <a href="http://en.wikipedia.org/wiki/Hypertufa" rel="nofollow">hypertufa</a> pots all the time... they work great.</p>
<p>Thank you for the suggestion. I will look into that.</p>
<p>I am the manager of an apartment complex we have a playground and i was thinking of putting these around it. What do you all think about that </p>
<p>The kids will love them!</p>
<p>These would be really nice around the complex.</p><p>What about using larger bottles or buckets? wander the aisles of your local hardware store and see what would be a good shape. </p>
<p>Definitely a fun idea, kids will love it and parents will chuckle.</p>
<p>may I know what is the name of the plant?</p>
<p>It's a type of Sempervivum. It's more commonly known as hen and chicks.</p>
<p>Echeveria genus. </p><p><a href="http://en.wikipedia.org/wiki/Echeveria" rel="nofollow">http://en.wikipedia.org/wiki/Echeveria</a></p>
<p>Looks so cute :)</p>
<p>Thank you!</p>
<p>Kawaii! Love these! </p>
<p>Thank you!</p>
<p>I think the cuteness factor is directly proportional to what is planted inside... nah, pretty much anything that gets planted in these things would be cute!</p>
<p>Its beautiful..Thanks for sharing :)</p>
<p>Thank you!</p>
